The dramatic loss of sea ice around Antarctica has occurred with the re-emergence of the Maud Rise polynya in the Weddell Sea ...

Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ...

A hole of open water, called a polynya, appeared in the winter ice of the Weddell Sea in Antarctica. It eventually grew to roughly twice the size of Vermont.

They found the polynya was brought on by complex interactions between the wind, ocean currents, and the unique geography of the ocean floor, transporting heat and salt towards the surface.

A polynya -- a Russian word that roughly means "hole in the ice" -- can form off the coast of Antarctica and last for weeks to months, acting as a refuge where penguins, ...

Scientists have solved part of a longstanding mystery on how a gigantic hole in Antarctica's sea ice formed. Scientists first discovered the mysterious hole, known as a polynya, in the 1970s.
